Toxicity of a Uniform Combined Bidirectional Hyperthermic and Perioperative Intraperitoneal Chemotherapy Regimen after Cytoreductive Surgery in 147 Peritoneal Surface Malignancy Patients

• BackgroundCurrently, the treatment of peritoneal surface malignancy is managed in selected patients by the combination of cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC). The chemotherapy agents utilized are selected from response rates in the treatment of gross disease and from pharmacologic studies. These agents are then subjected to morbidity/mortality studies to establish the safety of the treatment. The aim of this study was to analyze the morbidity and mortality of a new bidirectional hyperthermic and perioperative intraperitoneal chemotherapy regimen used after cytoreductive surgery.Materials and MethodsPatients (n=147) with peritoneal surface malignancy received a uniform treatment of cytoreductive surgery combined with intraoperative chemotherapy. HIPEC with mitomycin C and doxorubicin was supplemented with intravenous 5-fluorouracil and leucovorin. In 65 patients, additional early postoperative intraperitoneal (EPIC) 5-fluorouracil was added to the HIPEC for the first four postoperative days. The clinical factors were cataloged prospectively and any adverse events (AE) were tabulated. ResultsIn 85% of patients, complete cytoreduction was achieved. There was an increase in grade IV AE in patients with incomplete cytoreduction (p<0.04) and in patients receiving fresh frozen plasma (p<0.001). For both grades III and IV AE, a right colon resection increased morbidity (p<0.02) and chemotherapy treatment HIPEC plus EPIC increased morbidity, compared to HIPEC alone (p<0.05). The overall morbidity (grades I-IV) was 64% and mortality was 0.6%.ConclusionThe new bidirectional hyperthermic and perioperative intraperitoneal chemotherapy regimen used after CRS can be safely applied in peritoneal carcinomatosis patients.
